I am looking to get a box built and i was wondering if anyone could build me one in the next month or so.

Its a box for 2 15 RE XXX subs to fit in a 2002 Altima. I just started thinking up box designs but here is the link to my thread which explains everything im looking for:

http://www.caraudio.com/forum/showthread.php?t=207088

I also saw a custom box that somebody else built on here. Its design would be perfect for my trunk. The specs would have to be relevant to my trunk but the shape of it is exactly the type i need. Im not sure if this box would sound like garbage or not but here is this guys link too. I'd rather go with his box style but i have no idea about how it would sound.

i've got a box already made that would be perfect for ya... i think 4.2 cubes @32 hz. if you're interested PM me, and i'll get you the exact dimentions on it. shipping is gunna be a ***** though

Man you really need to look into 1 of those drivers or something smaller. I can design you a nice box ported for 1, but i don't know if 2 will even be ok sealed. Looking at your specs you will get somewhere around ~5.7 cu/ft sealed.

Thats what I was thinking. 1 ported would be more than enough. :cool:

ive already got 1 15 XXX in a nice *** box. I just wanted to get something with better SQ and deeper bass. I dont know if 2 12's would be much of an improvement so i figure i'd see about 2 15's. A bounus would be that i wouldnt have to mess with selling my sub and locating 2 12's with the right amp and all that. Would just make it much less complicated.

Thats why i was thinking about this design.

Back of the box could be around 26 inches long and 14.5 inches high.

The front of the box where the sub cone would stick out could be 35 - 39 inches long and about 18 inches high.

From front to back the box could be 23.5 inches deep

If you look at the box in that link you will see an angle. Unlike that box, my angle could start at about 3 inches from the back of the box until it meets the front.

So the box is 26 inches long in the back, the angle starts 3 inches in from the back. And at the end of the angles, they would meet up to the front of the box which is around 37 inches long.

Also, the height of the box which would be 14.5 inches in the back, could gradually get higher the closer we come to the front of the box. That gradual incline could probably start at around 8 inches from the back of the box(14.5 in. high) and could finish at the front of the box( 19 in. high). So, it would be angled at the sides and angled on the top as well.

This would make the most out of my trunk space. I have no idea how many cubes this would give me. I have no idea if this could be a good sounding box as i have no knowledge of creating a good sounding box.

my math might be completely off but that looks to me like about 6.5 cu. ft.

Where in FL are you? If your close to me, St. Pete, clearwater, or tampa, I'd be glad to build for you...

Okay, to be honest, if one 15" XXX isn't enough bass, let alone isn't clean or low enough, then there's something wrong with your system...and it isn't the speaker.

Maybe im gradually going deaf and it takes more and more for me to hear it.

I was thinking, maybe the box i have now is too big and it is restricting sound waves or something. How close is the sub in a ported box supposed to be to the trunk lid?
Its 8 or 9 in. away right now. I think i saw someone reccomend about 12 inches or so.

Hmm, im gonna see if i can get my hands on a 15 in. single sub box to hook my sub up to. Maybe the box isnt a good design for my car.

Question, as a general rule, is it the bigger the box, the more power you can give the sub or the opposite way around?

It's the opposite way around. The speaker can become more efficient, but after a certain point it has no damping from the box and will just proceed to overexcursion and mechanical failure.

Just throwing a sub in any box is a BAD idea, I completely argree with this statement:

As per my comment before if you put one of those drviers in a correctly designed box it will should be more then enough even if your going deaf.;)

What i meant was that i'd just throw it in whatever box they had at the audio store to see how it sounds. If it sounds as good or better in a cheapo (normal ported box) than i know something is wrong with my box and i can start looking to get another one made.

One question: will your proposed box actually be able to be put into the trunk or have to be built inside it? I have a 2000 Alty and your box specs would be pretty much be my entire trunk, but NO way to get it through the opening.

I did 2 15" RL-P's each in a 2.5^3 @30Hz box and even by building test boxes ahead of time I still had to cut some metal near the rear/bottom opening to get them in :eek:

Might want to look for subs that will work in a smaller enclosure or perhaps do a single 18" if you can make it fit.
